Learn why we have sea and land breezes. Almost anytime you go to the beach you will encounter some wind. This is because of the land and water heating up and cooling off at different rates.
Land warms up and cools off more quickly than water. Warm air creates a low-pressure area and cold air creates a high-pressure area. Air will always flow from high pressure to low pressure and this will generate wind.

Learn about the four Spheres of the earth.
The earth can be divided into four major spheres.
The biosphere which means life.
The hydrosphere which makes up all the water of the earth
The atmosphere which is the air of the earth
The geosphere which is all of the rocks, soil, and layers of the earth.

These four spheres of the earth allow life to exist on planet earth

Learn the difference between physical and chemical changes by observing real life examples.
Is mentos and diet cke a physical or chemical change? Actually it is a phase change so it is a physical change.
I include other example like breaking a piggy bank, fireworks, cutting hair and several other examples. The goal is to help you undertand the difference between a physical and chemcal change by looking at examples.

The cell membrane surrounds the cell and protects the cell, communicates with other cells, and controls what enters and exits the cell.
The cell membrane is made of phospholipids which have a polar and nonpolar end.
The cell membrane also has proteins and carbohydrates.
In this video, I cover what the cell membrane is made of and the structure and function of the cell membrane.

Learn how to code from DNA to mRNA to tRNA to amino acids.DNA is made up of four bases Adenine Cytosine Guanine and Thymine
Let's shorten this to ACG and T
A pairs with T and G pairs with C
So if we have this strand. It moves from 5 to 3
For a complementary strand, you will have
a will pair with t, t with a g with c and you can watch the rest.
Now messenger RNA is similar to DNA but instead of thymine, you will have uracil.
After decoding the mRNA and tRNA you can use an amino acid chart and find the correct amino acid.

At 2:21 I mislabel tRNA. Sorry for the mistake. Here is an updated video correcting the mistake.

In this video, I would like to show some examples of diffusion.
Diffusion is when objects move from an area of high concentration to an area of low concentration.
Check out this example, of diffusion.
You can another simple example of diffusion when you watch the food coloring diffuse into the water.
If you take an egg and soak it in vinegar and then place it in water, the water will diffuse into the egg causing it to get larger.
If you place sugar into coffee it will diffuse out into the coffee.
Watering plants diffuses the water into the plants
When you go into Starbucks and smell the coffee smell the smell of the coffee has diffused through out the coffee shop.
You can soak a gummy bear in water and the water will diffuse into the gummy bear. and it will get larger.
Those are several examples of diffusion.
When objects move from high concentration to low concentration.
Thanks for watching and MooMooMath and Science uploads a new Math and Science video everyday.

What is a ribosome? A ribosome is an organelle found in plant, animal, and bacteria cells.
They are very small yet very important because they make proteins. Ribosomes use a process called translation to make proteins.

If you would like to learn more about proteins and their importance this video will help.

Pathway of Air Flow
Our journey of oxygen into the lungs and back begins when the brain stem sends a message to the diaphragm which is a muscle under the lungs.
As the diaphragm moves down the lungs expand.

Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
This process is repeated over and over again.

Equivalent Fractions look different but measure the same thing! I place several equivalent fractions on a number line in order to help you see that they measure the same things. Remember, a fraction measures parts of a whole.

Learn how biogeochemical cycles work. Important elements along with molecules like water are conserved by moving between living factors called biotic factors and abiotic factors which are nonliving factors. You can remember the elements that have biogeochemical cycles using CHNOPS
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.
Each of these elements has its own unique cycle and path from biotic and abiotic factors.

Macromolecules are large molecules that help keep the cell alive. What are macromolecules? You may also hear the term biomolecules to describe these large molecules
Cells of animals and most living organisms have four main macromolecules that help keep their cells alive and functioning properly.
The four main macromolecules are carbohydrates, proteins, lipids, and nucleic acids.

Anaerobic Respiration Fermentation

Anaerobic respiration, also called fermentation, occurs when cells need energy but there is no oxygen for aerobic respiration. As a result, cells convert glucose into either ethanol or lactic acid.
Alcoholic respiration occurs in plants and yeast.
Lactic acid fermentation occurs in animals.

Protein synthesis in simple terms. I cover the steps of transcription and translation. The overall process involves DNA unzipping when RNA polymerase attaches and a strand of RNA is created. Rna is different than DNA because it contains the base Uracil instead of Thymine. This step is called transcription.
I next show the difference between transcription and translation by showing how the mRNA leaves the nucleus and attaches to a ribosome.
At the ribosome codons and anticodons put the amino acids together in the correct order to form the protein.

How do we breathe? The lungs and diaphragm work together to bring oxygen into the lungs and to move carbon dioxide out of your lungs.
The diaphragm is a large muscle that is found under your lungs. Your lungs are actually composed of millions of tiny air sacs and depend on the diaphragm in order to inflate
Your rib cage also helps out by having cartilage which allows the rib cage to expand and contract.
When you take a deep breath your diaphragm moves down and a low-pressure area is created and air flows into your nose and mouth. This process is your respiratory system hard at work.
Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.

As you exhale the diaphragm moves upward and carbon dioxide and airflows out.

How does oxygen enter the body. The respiratory system is designed to exchange oxygen for carbon dioxide. The respiratory system is vital for the production of ATP. The mitochondria uses oxygen in order to produce ATP. In addition, it is designed to get rid of the waster product carbon dioxide.

In this video, I show real-world examples of alleles.
An allele is different forms of the same gene which results in traits that look different.

A trait is a characteristic that can be passed from one generation to another.

The different forms of the same gene are the alleles
How about a couple more real-life examples

Eye color would be the trait
The different color of eyes would be the alleles

The trait is having hair

Black or blonde hair color

Your height is the trait
If you are Six feet or five feet tall

Allele different forms of the same trait.
